Doug Pederson backed struggling Philadelphia Eagles quarterback Carson Wentz following criticism from Hall of Famer Brett Favre.

Favre said the Eagles should have kept NFL Super Bowl-winning QB Nick Foles at the end of 2018 instead of giving Wentz a lucrative four-year, $128million contract extension.

Foles stepped up in the absence of injured star Wentz and guided the Eagles to their first Super Bowl title during the 2017 season, before leading Philadelphia back into the playoffs the following campaign.

But Wentz has since struggled in Philadelphia, where he entered the Week 9 bye leading the NFL in turnovers (16), interceptions (12) and sacks (32).

Wentz also ranks 32nd in completion percentage (58.4) and 30th in yards per attempt (6.2), however Eagles head coach Pederson defended the 2017 Pro Bowler.

"I respect his opinion and his words. Those aren't mine," Pederson said during Wednesday's news conference.

"Please don't put words in my mouth or we're going to have a problem. Carson's our guy, bottom line. End of story."

Through eight games this season, Wentz has completed 178 of 305 passes for 1,883 yards and 12 touchdowns.

In Philadelphia's 23-9 win over rivals the Dallas Cowboys in Week 8, Wentz was 15-of-27 passing for 123 yards, two touchdowns, two interceptions and four sacks.

The Eagles (3-4-1) top the NFC East, despite a losing record, ahead of the Washington Football Team (2-6).

Pederson added: "Carson's our guy. Carson was our draft pick. Carson's the guy that is going to carry us and lead this football team.

"Listen, everybody is entitled to their own opinion.

"Those aren't my words, those aren't Howie [Roseman]'s words, Jeffery [Lurie]'s words, those are his words. I respect that opinion.

"Whatever he wants to say, that's fine and we're going to remain friends. It doesn't bother me one way or another."
